Searching for the Annual Modulation of Dark Matter signal with the GENIUS - TF experiment
The annual modulation of the recoil spectrum observed in an underground detector is well known as the main signature of a possible WIMP signal. The GENIUS-TF experiment, under construction in the Gran Sasso National Laboratory, can search for the annual modulation of the Dark Matter signal using 40 kg of naked-Ge detectors in liquid nitrogen. Starting from a set of data simulated under the hypo...
متن کاملWIMP Annual Modulation with Opposite Phase in Late-Infall Halo Models
We show that in the late-infall model of our galactic halo by P. Sikivie the expected phase of the annual modulation of a WIMP halo signal in direct detection experiments is opposite to the one usually expected. If a non-virialized halo component due to the infall of (collisionless) dark matter particles cannot be rejected, an annual modulation in a dark matter signal should be looked for by ex...
متن کاملGenius and the Genius Tf: a New Observatory for Wimp Dark Matter and Neutrinoless Double Beta Decay
The GENIUS proposal is described and some of it’s physics potential is outlined. Also in the light of the contradictive results from the DAMA and CDMS experiments the Genius TF, a new experimental setup is proposed. The Genius TF could probe the DAMA evidence region using the WIMP nucleus recoil signal and WIMP annual modulation signature simultaneously. Besides that it can prove the long term ...
متن کاملWIMP search by the DAMA experiment at Gran Sasso
DAMA is searching for rare processes by developing and using several kinds of radiopure scintillators: in particular, NaI(Tl), liquid Xenon and CaF 2 (Eu). The main results are here summarized with particular attention to the investigation of the WIMP annual modulation signature.
متن کاملA Model Independent Analysis of the Annual Modulation Data
DAMA is searching for rare processes by developing and using several kinds of radiopure scintillators: in particular, NaI(Tl), liquid Xenon and CaF2(Eu). Here only the results released so far on the WIMP annual modulation signature are summarized and compared with results from other experiments, including the recent re-analysis of CDMS-I data. Next perspectives are also shortly addressed.
